Not all elements have unstable isotopes. Elements like fluorine and sodium have only stable isotopes. However, many elements do have both stable and unstable isotopes, where the unstable ones radioactively decay over time.

FAQs & Answers

  1. What makes an isotope stable or unstable? An isotope is stable if it does not undergo radioactive decay over time. Stability depends on the balance between protons and neutrons in the nucleus.
  2. Do all elements have unstable isotopes? No, not all elements have unstable isotopes. Some elements, such as fluorine and sodium, have only stable isotopes.
  3. Why do some isotopes decay radioactively? Unstable isotopes decay radioactively to reach a more stable nuclear configuration by emitting particles or radiation.
